This invention has for its object the provision of a strong anddurabl'e'breal'nng plow in which the point and share Wlll be cti'ectullyreenfor-ced and the depth to which the point may enter the ground may beeasily regulated;

The invention also has'for its object the provision of means whereby thebeam will be connected with the mold board so as to brace the same andthe handles will be mountedin' such a manner thatthe beam may be readilyadjusted to regulate the depthof the cut.

The invention isillustrated in the accomhpanying drawings and will behereinafter fully set forth.

In the drawings: Figure 1 is av side elevation of viewed from the moldboard side.

Figure 2 is'an enlarged rear elevation, the

a plow beam. and handles being broken away.

Figure 3 is an elevation viewing the land--' side side of the plow.

Figure 4 is a. horizontal section on the line of Figure 3.

vertically through the slot in thefront'end of the foot and the adjacentparts about on the line 55 of Figure 4.

Figure 6 is an enlarged detail view of the lower end of the standardwith the foot,

showing the moldboard side of the same.

Figure 7 is a perspective View of the from In carrying out the vided abeam 1 of approved form provided 5 at its front end with a clevis orother draft device 2 and having its rear end curved clownwardly to forma standard 3. The lower end of the standard is formed integral with a 7foot 4 having an openlng 5 through its rear 49 end whereby it may bepivotally attached to the landsid'e and having a slot 6 formed throughits front end on an arc concentric with said opening 5. a A lateralprojection 7 is formed on the foot 4L at the sidesof the" slot 6 and theinnerrface of this projection is formed with horizontally extendingcorrugations or teeth as shown at 8, the purpose of which willpresently'appear. The landside 9 is a straight rectangular bar oftheusual form disposed in the horizontal plane of the Figure 5 isanenlarged detail section taken invention there is pro-' foot 4 of thestandard at the outer side there of and connected therewith bytransverse bolts, as will be understood. Between the foot l and thelandside is interposed a frog 10 which has a longitudinalportion'substantial- 1y of the same form and dimensions as the lane-sideandsecured to the landside and the standard by the same bolts whichconnect the landside to the foot l of thestandard. At its front end thefrog is formed with a lateral wing: 11 which is-shaped to conform to therear of the mold board 12 and the share 13 and bridges the joint betweenthe share and the mold board, as shownclearly in Figure 2. The share 131s iorined integral wlth "thefpoint 14 and the point is formed with anabrupt rear end abutting'the front end of the landsidc, as shown at 15,the

line of merger between the share and the point being curved, as shown at16, and the frog having a similar curve uniting the wing 11 to the mainbar of the frog so'that the parts will be very efliciently recniorced,as willbc understood upon reference to Figure 4. To further reenforceand brace the mold board and the share an arcuate strap brace 1'? isprovided, the forward end of this brace being secured to the mold boardand the share adjacent the edge of the wing 11 and the rear end of thebrace being secured by the bolt passing throughthe landside, the frogand the opening 5 in the foot l, as will be understood'upon referenceto-Figure 4. The mold board is further braced by an angle strap bracket18 which has one arm secured'to the rearside of the mold board and itsother arm extendedrearwardly'adjacent the standard 3 and longitudinallyslotted, as indi'cated at 19 in Figure 3. The inner side of therearwardlyeXtending arm is further providedwith notches indicated at 20in Figure 2, and a washer 21 having mating notches is placed "againstthesame whercby when the securon the bolt and turned home against thewasher.

To the rear side of the mold board, approximately at the center of thesame, is secured a strap which has its upper portion twisted somewhat sothat one handle 26 may Cir be secured thereto. The other handle 27 issecured to a strap 28 which has its lower end secured to the side of thestandard 3 and projects somewhat therefrom at its upper end. This mannerof mounting the handles will permit them to be easily removed whennecessary without dismantling theworking parts of the plow, and thehandles are reenforced and prevented from dropping by bracing links 29which are secured at their front ends to the standard at the point whereit merges into the beam and have their rear ends adjustably secured tothe respective handles.

. It will be readily seen from the foregoing description, taken inconnection with the accompanying drawings, a very strong and durableplow which is not unduly complicated in its construction. By looseningthe nut 23 and the nut on the bolt through the hole 5 in the rear end ofthe foot, apivotal movement may be imparted to the foot t about saidbolt so that the front end of the beam 1 may be adjusted verticallyrelative to the plow point 14; and, of course, after the beam has beenset at the desired angle,

the nuts are again turned home. The corrugated construction of theopposed faces of the projection 7 and the washer 22 will relieve thestrain on the threads of the bolt 24: and maintain the beam in'theposition in which it has been set and thedepth of penetration by thepoint let may be thus easily regulated without requiring the driver toexert undue pressure upon the handles. The bracket 18 is obviouslyreadily adjustable to accommodate the varying angular relation betweenthe standard 3 and the mold board as the standard is adjusted in thejust described manner, and this bracket is located nearer the landsideedge of the mold board so that it will aid in resisting the thrust uponthe plow. The arcuate brace 17 and the frog 10 very effectuallyreenforce the point and the share and consequently prolong the life ofthe plow. The described adjustment permits the user of the plow to setthe point 14 to make the proper out under any circumstances and therebyavoid excessive wear upon that I have provided the point and the shareso that the necessity for frequently re-sharpening the point and theshare will be avoided.

Having thus described the invention, what is claimed is:

1. In a plow, the combination of a mold board, astandard at the rear ofthe mold board, a bracket secured to the rear side of the mold board andhaving a slotted member disposed against the inner side of the standard,said slotted member having a corrugated inner face, a washer fittedagainst said corrugated and slotted member and mating therewith, and asecuring bolt inserted through the standard, washer and said slottedmember to adjustably secure the parts together.

2. In a plow the combination of a plow body comprising a mold board, ashare and a landside, of a standard provided at its lower end with afoot disposed at the inner side of the landside and extending rearwardlylongitudinally thereof, means for pivotally connecting the rear end ofthe foot with the landside, and means at the front end of the foot forlocking the foot in its position of angular adjustment. Y

3. In a plow comprising a mold board, a share and a landside, a standardprovided at its lower end with a foot disposed at the inner side of thelandside and extending longitudinally of the same, a lateral projectionon the inner side of said foot at the front end thereof, said projectionhaving horizontal corrugations on its inner face and'there being anarcuate slot formed through the projection and the front end of thefoot, means for pivotally securing the rear end of the foot to thelandside, securing means inserted through the landside and through thearcuate slot in the foot and said projection, and handles connected tothe standard.

In testimony whereof I affix my signature.
